I mean, it's a fair question. I think a lot of people would think of the RDBMS, but obviously they don't have 180k people working on that. They do all sorts of other stuff as well, of course, but I'm not sure people necessarily think of that when they hear 'Oracle'.
A database, plus American SAP, plus a sort of also-ran AWS-type thing, plus the sad remains of Sun, is about it.
